Känselsensorer

Känselsensorer, often translated as tactile sensors or touch sensors, are devices designed to detect and measure physical interaction with their environment. These sensors simulate the sense of touch found in biological organisms, allowing machines and systems to perceive pressure, texture, temperature, and deformation. They are crucial components in robotics, enabling robots to manipulate objects with precision, avoid collisions, and interact safely with humans.

There are various types of känselsensorer, each utilizing different physical principles. Capacitive sensors detect changes in capacitance caused by proximity or contact, often used for touchscreens. Piezoresistive sensors change their electrical resistance when subjected to pressure. Piezoelectric sensors generate an electrical charge when deformed by mechanical stress. Strain gauges measure deformation by detecting changes in electrical resistance as a material is stretched or compressed. Other types include optical sensors that detect light variations due to contact and thermal sensors that measure temperature.

The applications of känselsensorer are diverse and expanding. In manufacturing, they are used for quality control and automated assembly. In prosthetics, they provide users with a sense of touch, improving dexterity and control. In vehicles, they can detect impacts or monitor tire pressure. The development of more sensitive, durable, and cost-effective känselsensorer continues to drive innovation in fields requiring sophisticated human-machine interaction and advanced robotic capabilities.
